Coming in late to the 18z, anyway slightly north in the near term, over Turks and caicos Friday morning, Landfall near Key Largo Cat 5 Sunday morning, and rides up the entire spine of Florida inland, still a major hurricane over Orlando when it moves there overnight Sunday into Monday, the up to just west of Jacksonville Monday morning, still a hurricane, and doesn't give up hurricane strength until around Augusta, GA or slightly north of there Tuesday morning.

Today's 18z is faster than yesterday's 18z.

Good, it moves fast, bad, category 5 winds and surge dwindling to Category 3 hitting the entire east coast of Florida and well inland. Those in south florida would start to see some of Irma's bands Saturday, with the worst not being until Sunday morning.
